Last year we announced our smart contract oracle that we dubbed “Snopes Meets Mechanical Turk on a Blockchain”. Today we’re excited to tell you about the mainnet release of this project, now called Realitio. Realitio is a crowd-based oracle which relies on a system of escalating bonds to generate correct…
